How to disable GPU in Linux?
Hi everyone, I got a free laptop with a strong 3rd gen i7 and GT630m GPU. The battery life is decent for basic use on Linux Mint, lasting about 2½ hours. I’m thinking of turning off the dedicated graphics card since integrated graphics work well enough. I’ve also set up a trusted battery management tool (TLP) and followed some standard tips like disabling Bluetooth and lowering screen brightness. How can I disable the GPU to extend battery usage further?
Enable Optimus. There are various instructions based on the distribution. You shouldn't turn it off, just ensure it's active.
You just set up the drivers and chose Intel's built-in graphics over GeForce. Issue fixed!
Bit of an old thread but there IS optimus and primus. Bumblebee can use either. Difference is one uses direct while the other is indirect rendering (VirtualGL backend). Fun fact you can use the same concept to remotely offload GPU rendering from a low end device too.
